Seems to me that if GM was looking at saving their reputation, customers and vehicle status, they would pay the lesser of what it would take to fix the vehicle. If they are unable to repair the vehicle by fixing the SU4 axle, it would be cheaper to replace the axle with the SU5 axle that has no issues than to face a barrage of Lemon Law suits. Most of the time, a Lemon Law suit that does not go the customers favor, that customer goes and buys a truck from a different manufacturer. Yes, every manufacturer will build a vehicle that will have issues. It boils down to what the manufacturer classifies their customers as. Most customers that like new vehicles are like me. All I want is a vehicle that will give me 5-7 years of good service, then I trade it in on another. I am past the age of buying a used vehicle with over 100k miles that might last 2-3 years, costing me more and more money to keep going. So, in my case, in the long run, it is cheaper for me to buy a new or newer vehicle. (PS. I have to buy the wife a new one too, and yes, she happens to like GM also... ) Sorry for the blah, blah, blah... but this is all in my opinion.

Nothing that small can change the VIN#. It is just a parts replacement modification. It would just change the vehicle build sheet information.
